Hi,
I have an LED which when I plug in just flickers randomly even with no flicker unit, I have tested the same equipment with other LEDs and they are all fine. This is very annoying as it is a search light! Does anyone know what he problem is / how to fix it?

He may be right! Flicker LEDs are made for candle lamps, but they are usually only for AC mains lamps! ALL LEDs flicker if you use them on an non-rectified voltage, cos the voltage is constantly switching on and off. The flicker rate is usually between 50/60 to 120Hz so almost all people will never notice it. If you are using a DC supply it should come on when it has sufficient voltage and current and stay on. UNLESS - it is a DC type with a tiny 'flicker chip' built in! Then your only option is to use it for a signal lamp😉Otherwise I suspect you may need to reduce the series resistor slightly to push more current through it to keep it on.What type of LED is it? Do you know the manufacturer and type number?Cheers Doug 😎

Hi SkipperI have just found exactly the same problem with a LED on my Trent which I am doing some rework on. It's not a constant flicker more a random dimming followed by a couple of flickers. The electrical connection is OK and the problem was with the LED. It's in a tight space and I had damaged the leads into the LED resulting in the fault. I agree with Sonar and believe your best solution is to replace the faulty LED with another if you are sure the electrical connection is OK.Dave
